The organisation's ACT branch fielded 4156 phone calls and 1198 online reports in the first six months of this year, a 20 per cent jump on the same period in 2013.

Chairman Bryan Roachhas joined forces with territory police and urged community members to continue to come forward with any information they think could help to halt illegal activity or nab an offender.

The two agencies have launched a new campaign, which includes Crime Stoppers' contact details being emblazoned on an ACTION bus, to raise awareness of their joint effort to fight crime in the capital.

"Crime Stoppers is a partnership between police, media and the community, and the community's role is to recognise that we have to take action to report crime, criminal activity and criminals," Mr Roach said.

"We need to be aware we have crime in our community and we all have a responsibility to keep the community safe."

Crime Stoppers is an independent, non-profit community organisation that seeks to provide safe methods for crime information to be reported anonymously to remove fear of retaliation.

Although the organisation works very closely with police, it is a separate entity and members believe part of their role is to keep police accountable.

The organisation runs a hotline and users can also fill in an online form and upload images to an online reporting page.

Mr Roach said an increase in crime reports was likely due to climbing levels of online engagement from mobile devices, such as smartphones and tablets, and social media.

The organisation offers rewards of up to $1000 for crime information, although Mr Roach said they were rarely requested by members of the community.

"Most people report what they know because it's the right thing to do, not for a reward," he said.

ACT deputy police chief David Pryce encouraged Canberrans to report anything they saw as suspicious, no matter how insignificant it might seem.

"A lot of people know about Crime Stoppers but they don't know how important their piece of information might be.

"Every piece of information might be the piece of the puzzle that helps solve the crime."

He said community reports often helped to prevent or curtail crime, which had been the case in recent police campaigns that targeted illicit drugs and firearms in the territory.

Police paired with Crime Stoppers this year on a six-month operation that targeted illicit firearms in the capital.

That campaign saw police execute 25 search warrants and seize a cache of weapons that included 25 guns, 11 replicas and more than 3500 rounds of ammunition.

There was a 65 per cent increase in crime reporting on illicit drugs and other drug use during a four-month joint campaign that ended in November last year.
